Summary

To keep their computer models from drifting off into climates quite unlike today's, climate modelers have gotten in the habit of fiddling with fudge factors, arbitrary "flux adjustments." But now researchers at the National Center for Atmospheric Research in Boulder, Colorado, have developed a model that gets it right without flux adjustments. The first results from this model imply that future greenhouse warming may be milder than some other models have suggested--and may take decades to reveal itself.
